Method and system for sharing content files using a computer system and data network

ABSTRACT

A system for distributing digital content obtained from a variety of sources in a variety of formats is described that utilizes a content distribution system configured to receive and store the content files, convert the content file both into a standardized format file and into a thumbnail file, and associate the content with one or more tags that can signify characteristics or relevant facts about the content file. Users of the system select one or more tags on their remote devices in order that the content distribution system automatically transmit to the remote device thumbnail images of those content files that match the selected tags. Users can then select the thumbnail image in order to cause the system to transmit to the remote device the standardized format version of the content.

FIELD OF INVENTION

This invention is a system related to uploading and sharing content files between users. For convenience, the system is referred to herein as “Pushfor.” Pushfor is a platform to allow content from one user to be ‘pushed’ to other users via a cloud computing architecture. The system provides a flexible way for users to specify channels, so that they automatically become recipients of certain kinds of content. The system also permits users to specify recipient lists to receive particular pieces of content. Content may be controlled in order to maintain security over the content or maintain restrictions in order to be compliant with local copyright law.

DETAILED DESCRIPTION

The Pushfor system is a system for sharing content files comprised of:

A conversion subsystem configured to receive a content file and convert the content file into a standardized format file and into a thumbnail file;

An input subsystem to receive at least one tag data to be associated with the received content file;

A data storage subsystem configured to store the conversion output of the conversion subsystem and to maintain a data structure that associates the standard format of the uploaded file with the thumbnail file of the uploaded file and to further associate the stored files with the at least one tag data;

A routing subsystem configured to receive at least one channel criteria associated with a corresponding at least one recipient user and to determine whether the at least one tag data conforms with the at least one recipient user channel criteria, and in dependence thereon, transmit a data message to the at least one recipient user, the data message being comprised of the thumbnail file; and

A transmitting subsystem configured to transmit the converted file to the at least one recipient user in response to a request from the at least one recipient user to view the converted file associated with the thumbnail file.

The system is further comprised of:

A security subsystem that determines whether the at least one recipient user is permitted to access the converted file, and in dependence thereon, preventing transmission of the message.

The system is further comprised of:

At least one player subsystem that operates on at least one device corresponding to the at least one recipient user, where the player device is configured to receive the converted standard content file from the transmitting subsystem and to prevent the at least one recipient user from accessing the file upon a restriction condition occurring.

The process of Pushfor involves two types of users: Content transmitting users, who may be authors, editors or authorized persons controlling a document (“transmitting users”) are users who upload content so that it can be shared with others and content recipient users (“recipient users”) are users who view content transmitted to them using the Pushfor system.

The transmitting user uploads content from their mobile or PC or other device and tags each piece of content with descriptive tags e.g. ‘building’ as shown in FIG. 27, so that it can be found easily by recipient users. Tags may include any kind of alphanumeric string that is associated with the content. Each piece of content is given a unique ID and the tags are stored as metadata associated with the content. Content needs to be displayed on a recipient user's device without requiring the associated apps being present e.g. Word for doc files other kinds of files. This is accomplished by converting all of the uploaded content into a standard format that can be used across all of the recipient user's respective devices. In the preferred embodiment, it is HTML5 format so that it can be viewed on new browsers and mobile devices that are HTML 5 compatible, regardless of the underlying hardware or operating system. The process of conversion can be undertaken on a separate server and processed using a queue system. The HTML5 is stored alongside a thumbnail view and an encrypted copy of the original file onto a file system (one example is the Amazon S3™ system). An transmitting user can set various attribute values to be associated with the content so that it has different properties when displayed to a recipient user. This could include password protection, restriction of download, hidden from searches or prevention of it being forwarded. The setting of attributes doesn't change the content but only how it's viewed or operated by a recipient user.

Transmitting users and recipient users can create custom channels which groups content based around tags and users. A channel doesn't contain any data (like a drive folder) but references content using their tags or an transmitting users' user name. An example of a channel could contain tags ‘painting’, ‘drawings’, ‘sketches’ by the user ‘Leonardo’ and the channel could be called ‘Leonardo da Vinci artwork’. In the preferred embodiment, the recipient user maintains an account on the central server that contains at least one channels specified by the recipient user. This would be a data structure associated with the user that specifies a list of criteria for that channel. Transmitting users also upload content into the system and it is converted, and tag data associated with that content. When the recipient user accesses the PushFor system from the remote device and selects their channel, the system runs a search for all content whose tag data matches or satisfies the criteria comprising the recipient user's channel. That search result is transmitted to the recipient user's device in the form of one or more thumbnail images, which may also constitute hyperlinks to select in order to download the converted file so it can be viewed.

Recipient users are shown content as thumbnails images of one of the pages of the original file so they can see lots of references to content on one screen. The platform looks at the content attributes and then changes how that content can operate with the display program. An example is if the transmitting user has input commands into the system to associate controls to a particular piece of content that disabled forwarding or downloading then the recipient user will be unable to do the restricted operations on that piece of content. The content is not changed to undertake this operation.

Transmitting users can share their content within the predefined channels using an option to ‘share the channel’. As a channel is shared the platform prompts if the transmitting user wants to change the tagged content to become hidden. This process is done because some transmitting users may wish to share content that is private and not available to other users but have forgotten to set the content to be hidden when it was first uploaded. Next the platform requests an optional access password from the transmitting user to secure the channel. The platform generates a unique platform ID (“PID”) and URL (“channel URL”) which is given to other recipient users. The channel ID and hash of the access password is stored in a database for later use. The channel URL would look something like this: www.pushfor.com/channel.php?pf0000000001 (“channel URL”)

The recipient user receives and clicks on a channel URL which takes them to the Pushfor website. The platform detects from a cookie on the recipient user's local browser operating on their device if they have already got an account. If the user is new then they will be guided through a sign up process or logged in. The platform takes the channel ID from the URL and reads from a database the optional password and then prompts the recipient user to grant access. If the password input by the recipient user is valid then the channel name that the transmitting user set is read and displayed in the channel bar on the screen. The platform reads from a number of tables to determine the filters set for the channel. The filters are then used to parse a NoSQL metadata database to find the content IDs that match the filters. The content ID numbers act as references or unique pointers into an Amazon S3 bucket or data structure that holds a thumbnail view of the content, a HTML5 version for viewing purposes and an encrypted and compressed copy of the original file. The recipient user's user ID is stored in a database to record when, where and how they have viewed the transmitting user's channel. The transmitting user can view the recipient user access information and block access to a channel to specific users if required.

Content that is uploaded may have more than one tag associated with it. The content owner can upload the content and then select to tag it and associate a label with the tag. The user can either select pre-existing tag labels or create their own tag labels. For example, a pre-existing tag could include a reference to an “image” or “document”, while a user tag could be “Summer Vacation 2013.” The tags can also be labeled with the user name, or some other subject describing the content or content type. Any number of tags can be attached to a content item. Automatic tagging may also be used. In this embodiment, a date/time stamp is attached as a label to a tag. In other embodiments, the system can run a facial recognition software application to identify persons in an image comprising the uploaded content item and automatically associate tags with the content item that are labeled with the identities of the detected persons.

The content that is uploaded is converted into a file type that can be viewed on any device. In the preferred embodiment, the content is uploaded and converted into a high-resolution image so that as a user views the document, they can zoom in and still have sufficient fidelity. In one embodiment, the image is converted into svg format or into PDF format. In another embodiment, the content image is converted into a lower resolution thumbnail image for use when displaying a catalog of content.

In yet another embodiment, the server that distributes the content to recipients can maintain analytical data that indicates which content was selected for viewing and for how long it was viewed. In this embodiment, content selection requests that are received are logged in a database so that a data record associated with the content captures the time the content was transmitted and the period of time until the next selection occurs or the application is exited. The display application running on the recipient user's device can also run a timing function in javascript and send the time value up to the server with appropriate identifiers to tie the value to the content and the viewing user. This elapsed time is stored in the data record associated with the content. The information may be used in the aggregate to show analytical aspects of content use by the users. The data record may also store an identifier associated with the viewing user so that characteristics of the viewing users may be correlated with their selection of content or their use of the content.

In one embodiment, the content owner can control other metadata associated with their uploaded content that controls how it is shared. In this embodiment, metadata options may be selected for the uploaded content in order to encode use privileges and/or permissions to further share the content. In addition, the sharing of content can either be by content or by reference. In the former, the viewing user receives the content as a file. In the latter, a hyperlink is transmitted to the viewing user who then can view the content via the activation of the hyperlink.

The hyperlink that references the content is a link to a webservice that shows image or images in an environment, preferably an app operating on the viewing user's device or an internet browser. When the link is activated, the link brings down scripts from the service that launch the user interface that interacts with the servers that hold the content. The viewing user can view the image that is the content, but that user cannot save it to the local device or modify it, unless the appropriate permission values are associated with the content. The script running the browser or app reacts to parameters representing the privilege settings that are downloaded from the server along with the content image.

The system provides the appearance of content occupying a channel. A channel is a set of tag values. If a person uploads content with matching tag values, that content is distributed to all viewing users that subscribe to those tags. The distribution system operates logical filters that lets content be displayed where tags associated with the content fit the filter. A channel is essentially a channel filter. As a result, a recipient user or content owner can create a channel by simply specifying a list of filter criteria and associating it with a channel name or index. Any content that meets the criteria will then appear in an indexed presentation when that channel is selected. The users can create multiple filter sets, each one being its own channel and having a name. Content can be private, or channel with a password protection, or public.

On IOS™ device, the App does the rendering of the image representing the content, but content and/or its image cannot be moved out of the sand box that comprises the App operating environment. More generally, on an Internet browser, the system uses HTML 5. In the case of a browser, the browser refresh button reloads the content comprising the channel for display. In the preferred embodiment, the scripts operating in the App or on the browser transmit a load command to the server in order to refresh the display on a push basis.

Push Feature: In yet another embodiment, the system can be configured to automatically push content to recipient user's devices. In this system the user retain security control and analytics without relying on email processes to transmit content.

The process flow works as follows. The sending user, e.g. the transmitting user, goes into a large view and clicks the link menu icon. As shown in FIG. 2, the sending user clicks “push” and as a result an interface window popups up, which is the push window. The push window allows the user to enter multiple identifiers of multiple corresponding system users who are to receive the content that the user seeks to transmit (e.g. the recipient users). In the preferred embodiment, the window is comprised of an “add” button, which when actuated, causes a list of users that are associated with the transmitting user to be displayed. The transmitting user can then select one of these users and as a result, cause that selected user to be added to the transmission recipient list of recipient users. The user then actuates a button in the window, preferably identified as “push”. The system checks the validity of the receiving user identifier. If it is correct, the window responds by displaying a notification that the content has been pushed. In the case where the recipient is alerted that the content file has been pushed to them, when they access the file, the system transmits an alert message to the sending user.

From the recipient user's standpoint, the incoming pushed content is routed to a channel that is named “INBOX.” This channel cannot be deleted or renamed because it is the repository for received content that is not part of any other channel set up by the recipient user. The file that was pushed now appears in the INBOX channel. On the recipient user's (e.g. viewer's) user interface, a notification is displayed to state that “<SENDING USER> has pushed you a file”. Alternatively, an icon representing the transmitted file may be displayed with the name of the transmitting user. When the recipient selects the file, either by actuating the icon representing the file or otherwise entering a command to view the file, the file is displayed on the recipient's display device.

In yet another embodiment, if a content file that has been pushed permits forwarding, then the receiving user can select that received file to be pushed in the same manner as presented above. If the transmitting user deletes the original pushed file, then it will be removed from the recipients ‘INBOX’ and also other forwarding recipients that is has been pushed to.

The same feature can be used to push content to a mobile user. As an example if a company publishes some content onto a website or social network. A recipient user operating a mobile device can be guided to download the Pushfor mobile app as a result of clicking on a hyperlink on the webpage. By establishing a default or automatic login identity on the system, they will receive into their INBOX on their mobile device operating the Pushfor viewing app any content pushed to that identifier. This same process could also be triggered with a QR code printed on a poster or billboard.

Content Control: The transmitting user of content that uploads the content into the system can set controls on the content that they push. For example a document can be pushed to a recipient user and have certain restrictions placed on it. In one embodiment, the content files that have permission restrictions can be pushed to other users and retain the restriction settings, for example, restrictions on copying or re-transmission or printing. Other restrictions can include time-to-live or other kinds of expiration mechanisms. In yet another embodiment, where a user seeks to push a content file with a permission level or other domain of permitted distribution, the system can check that the specified destination user is a member of that domain and also has the correct permission level to access the document. If that logical condition is satisfied, the system pushes the content to that user. If not, it does not. For example, the user identifier may be associated in the system with an IP address range of an authorized computing device or network. In another example, the user identifier may be associated with an address whose email domain is known as an authorized domain.

The content file can retain restrictions that are associated with the file. There restrictions are checked by any device receiving the content using the system. Examples of restrictions include:

-   -   Restriction on how many views the file can have.     -   How long the file can be viewed for.     -   Causing the file to be deleted from an inbox when viewed once.     -   Limitations on when the file may be viewed.     -   GeoIP restricted viewing which prevents files being opened and         viewed in restricted locations, either outside a company campus         or in another country. This is accomplished by the system         detecting either the location of the device by means of its         location services or detecting the IP address of the device and         mapping the IP address to an approximate location.         Operating Environment:

The user's computer may be a laptop or desktop type of personal computer. It can also be a cell phone, smart phone or other handheld device, including a tablet. The precise form factor of the user's computer does not limit the claimed invention. Examples of well known computing systems, environments, and/or configurations that may be suitable for use with the invention include, but are not limited to, personal computers, server computers, hand-held, laptop or mobile computer or communications devices such as cell phones and PDA's, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.

The system and method described herein can be executed using a computer system, generally comprised of a central processing unit (CPU) that is operatively connected to a memory device, data input and output circuitry (I/O) and computer data network communication circuitry. A video display device may be operatively connected through the I/O circuitry to the CPU. Components that are operatively connected to the CPU using the I/O circuitry include microphones, for digitally recording sound, and video camera, for digitally recording images or video. Audio and video may be recorded simultaneously as an audio visual recording. The I/O circuitry can also be operatively connected to an audio loudspeaker in order to render digital audio data into audible sound. Audio and video may be rendered through the loudspeaker and display device separately or in combination. Computer code executed by the CPU can take data received by the data communication circuitry and store it in the memory device. In addition, the CPU can take data from the I/O circuitry and store it in the memory device. Further, the CPU can take data from a memory device and output it through the I/O circuitry or the data communication circuitry. The data stored in memory may be further recalled from the memory device, further processed or modified by the CPU in the manner described herein and restored in the same memory device or a different memory device operatively connected to the CPU including by means of the data network circuitry. The memory device can be any kind of data storage circuit or magnetic storage or optical device, including a hard disk, optical disk or solid state memory.

The computer can display on the display screen operatively connected to the I/O circuitry the appearance of a user interface. Various shapes, text and other graphical forms are displayed on the screen as a result of the computer generating data that causes the pixels comprising the display screen to take on various colors and shades. The user interface also displays a graphical object referred to in the art as a cursor. The object's location on the display indicates to the user a selection of another object on the screen. The cursor may be moved by the user by means of another device connected by I/O circuitry to the computer. This device detects certain physical motions of the user, for example, the position of the hand on a flat surface or the position of a finger on a flat surface. Such devices may be referred to in the art as a mouse or a track pad. In some embodiments, the display screen itself can act as a trackpad by sensing the presence and position of one or more fingers on the surface of the display screen. When the cursor is located over a graphical object that appears to be a button or switch, the user can actuate the button or switch by engaging a physical switch on the mouse or trackpad or computer device or tapping the trackpad or touch sensitive display. When the computer detects that the physical switch has been engaged (or that the tapping of the track pad or touch sensitive screen has occurred), it takes the apparent location of the cursor (or in the case of a touch sensitive screen, the detected position of the finger) on the screen and executes the process associated with that location. As an example, not intended to limit the breadth of the disclosed invention, a graphical object that appears to be a 2 dimensional box with the word “enter” within it may be displayed on the screen. If the computer detects that the switch has been engaged while the cursor location (or finger location for a touch sensitive screen) was within the boundaries of a graphical object, for example, the displayed box, the computer will execute the process associated with the “enter” command. In this way, graphical objects on the screen create a user interface that permits the user to control the processes operating on the computer.

The system is typically comprised of a central server that is connected by a data network to a user's computer. The central server may be comprised of one or more computers connected to one or more mass storage devices. The precise architecture of the central server does not limit the claimed invention. In addition, the data network may operate with several levels, such that the user's computer is connected through a fire wall to one server, which routes communications to another server that executes the disclosed methods. The precise details of the data network architecture does not limit the claimed invention.

A server may be a computer comprised of a central processing unit with a mass storage device and a network connection. In addition a server can include multiple of such computers connected together with a data network or other data transfer connection, or, multiple computers on a network with network accessed storage, in a manner that provides such functionality as a group. Practitioners of ordinary skill will recognize that functions that are accomplished on one server may be partitioned and accomplished on multiple servers that are operatively connected by a computer network by means of appropriate inter process communication. In addition, the access of the web site can be by means of an Internet browser accessing a secure or public page or by means of a client program running on a local computer that is connected over a computer network to the server. A data message and data upload or download can be delivered over the Internet using typical protocols, including TCP/IP, HTTP, SMTP, RPC, FTP or other kinds of data communication protocols that permit processes running on two remote computers to exchange information by means of digital network communication. As a result a data message can be a data packet transmitted from or received by a computer containing a destination network address, a destination process or application identifier, and data values that can be parsed at the destination computer located at the destination network address by the destination application in order that the relevant data values are extracted and used by the destination application.

The invention may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices. Practitioners of ordinary skill will recognize that the invention may be executed on one or more computer processors that are linked using a data network, including, for example, the Internet. In another embodiment, different steps of the process can be executed by one or more computers and storage devices geographically separated by connected by a data network in a manner so that they operate together to execute the process steps. In one embodiment, a user's computer can run an application that causes the user's computer to transmit a stream of one or more data packets across a data network to a second computer, referred to here as a server. The server, in turn, may be connected to one or more mass data storage devices where the database is stored. The server can execute a program that receives the transmitted packet and interpret the transmitted data packets in order to extract database query information. The server can then execute the remaining steps of the invention by means of accessing the mass storage devices to derive the desired result of the query. Alternatively, the server can transmit the query information to another computer that is connected to the mass storage devices, and that computer can execute the invention to derive the desired result. The result can then be transmitted back to the user's computer by means of another stream of one or more data packets appropriately addressed to the user's computer.

 26. The method of claim 25 further comprising: Selecting at the server a subset of the selected at least one recipient users where a restriction condition encoded in the at least one content tag data associated with the document file applies to the channel tag data associated with the at least one recipient users in the subset and in dependence on such selection of the subset, prevent transmission of the document file to the remote devices associated with the selected subset of recipient users.
 27. The method of claim 26 where the restriction condition is: the channel tag data associated with the selected subset of recipient users not including values indicating permission to access the document file.
 28. The method of claim 26 where the restriction condition is one of: the expiration of a predetermined amount of time from receiving the request to view the image format file and the remote device being in a restricted location.
 29. The method of claim 26 where the restriction condition is that the IP address of the remote computer not being within some predetermined range associated with the document file.
 30. The method of claim 26 where the restriction condition is that a domain associated with the selected subset of recipient users not being associated with a permissible domain associated with the document file.
 31. The method of claim 26 where the restriction condition is how long the image format file can be viewed for on a single receiving remote device.
 32. The method of claim 26 where the restriction condition is causing the image format file to be deleted from the remote device upon being viewed once.
 33. The method of claim 26 where the restriction condition is limitations on time periods when the image format file may be viewed.
 34. The method of claim 26 where the restriction condition is limitations on geographic locations of the remote device where viewing of the image format file is permissible.
 35. The method of claim 25 where the at least one content tag data associated with the image format file is comprised of data encoding use permissions and the method is further comprised of verifying whether the at least one recipient user associated with the remote device is associated with a user permission value that conforms to the use permissions comprising the at least one first tag data associated with the image format file and in dependence thereon, either causing or preventing transmission of the data message.
 36. The method of claim 25 where the method is further comprised of: the display program receiving the image format file from the transmitting module on the server and preventing the at least one selected recipient user from accessing the image format file upon the display program detecting a restriction condition.
 37. The method of claim 25 whereby activation of the hyperlink by the selected at least one recipient user using the associated remote device causes computer code to be downloaded to the remote device causing such computer code to operate on the remote device, and in operation retrieve and display the image format file and prevent the image format file from being stored or modified on the remote device.
 38.
